Impressive, it's the first time I see something with agents which is actually useful. Thanks

[@unclecode]

Thank you, dear Mervin. I really appreciate your review of my library. Honestly, there's no way I could explain my library and its integration with another cool library in less than 20 minutes. Yet, you managed to do it in just 7-8 minutes. That's your incredible superpower. I'm trying to learn from the way you summarize and explain things 😆. Great job. By the way, I'm happy to see it engaging with your PraisonAI library and look forward to more collaboration. Kudos.

hey while installing this i got following error do you know why it happens. how can i solve it? raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['C:\\Users\\99559\\AppData\\Local\\Programs\\Python\\Python311\\python.exe', '-m', 'pip', 'install', 'spacy', '--no-deps']' returned non-zero exit status 1. [end of output] note: This error originates from a subprocess, and is likely not a problem with pip.

@@YTber1 can u make an issue about this in repo?

[@YTber1]

@@unclecode ok!

Will be nice to see on what is possible to be accomplished without spending money on groq, OpenAI or Anthropic.

[@john_blues]

Interesting. Web crawlers, even automated ones are old technology. The addition of the LLM is powerful. It allows a more focused semantic search. An app like this also lowers the barrier for use as good web crawlers took a bit of technical knowledge.

[@yazanrisheh5127]

Hi Mervin. Can you do a video on building a RAG streamlit application for multi document types like PDF, CSV etc...

[@john_blues]

You were moving pretty fast. How was praisonai using the webscraper tool you created?

[@danielimonikhe1053]

Hi, can open-source LLms be used or just open AI?

[@farexBaby-ur8ns]

Think selenium testing cld leverage the use of this, or perhaps I am not in the know with new ai way or app testing

[@gnosisdg8497]

what about using ollama and any llm model as well? or any local llm model what so ever?

[@theunknown2090]

Ya if u get the prompts and the steps then run u can use any llm. Only depends on how capable the llm is.

[@unclecode]

Simply you pass "ollama/MODEL_NAME" for the model name and "no-token" for token, it works well.

[@godwinspeaks]

wow

[@Derick99]

Is there privacy concerns here or since is all publicly accessable its fair use?

[@rezashah22]

Thanks Marvin. Can we crawl entire site? for example for an ecommerce site, get products information such as title, description, price, image_url? Can we tell crawl4ai to follow the links?

[@unclecode]

Yes, the crawl result is an object that contains website metadata, external/internal links, media elements, markdown version, extracted content based on extraction strategies, and more. Please refer to the documentation for additional details.

[@rezashah22]

@@unclecode Thanks for the reply. Do you have examples how to scrape an entire site?

[@vijayakaja5001]

@@rezashah22 do you found any example?

[@unclecode]

@@rezashah22 Already added to the backlog to include in our example folder, should be done in a week or two.

[@darkreader01]

how can we crawl websites that need authentication? Can we add cookies?

[@SprintDock]

You could take the raw html from a logged in page

[@unclecode]

Crawl4AI offers several hooks, one positioned right before retrieving the URL. Here, you have access to the Selenium instance to implement your custom code for different purposes. The documentation contains an illustration of this functionality. It's worth noting that you can execute JS code on the page in case an interaction is required to access the data you need.

[@puneetxaxa1777]

How good is it for cralwing 2000 web pages of 5 different website?

[@unclecode]

We are conducting a stress test to ensure excellence. Currently performing well, we are implementing a scheduling/queue feature for bulk crawling, which will be available soon.

[@williamwong8424]

can this be done on intranet pages?

[@unclecode]

Yes, any url address (local, LAN, or WAN) which is accessible on ur machine, should be ok.

[@tonywhite4476]

What's the token cost?

[@MervinPraison]

It is based on the list of URls you provide and amount of content in each URL. You can also integrate Groq or Other LLM Providers.

[@MeinDeutschkurs]

Have to test the crawler. I‘m interested in how it manages robot.txt/robots meta tag, and how it handles smart bot recognition.
